Bit Operations using Macros

Code

#include <stdio.h>
#include <stdint.h>

// Define bitwise macros here

uint8_t modify_register(uint8_t reg) {
    // Apply operations in order
    //set bits 2 & 7 
    reg|=(1<<2);
    reg|=(1<<7);

    //clear bit 3
    reg&=~(1<<3);

    //toggle bit 5
    if(reg&(1<<5))
        reg&=~(1<<5);
    else
        reg|=(1<<5);

    return reg;
}

int main() {
    uint8_t reg;
    scanf("%hhu", &reg);
    printf("%u", modify_register(reg));
    return 0;
}
